1925 argument instead of a const uint8_t *buf / int buf_size pair.

1938 PIX_FMT_BGR32_1 are now macros.
1939 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1940 Re-sort the enum PixelFormat list accordingly.
1941 This change breaks API/ABI backward compatibility.
1943 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1944 Add the enum PixelFormat values:
1945 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1946 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1948 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1949 The Mersenne Twister PRNG implemented through the av_random* functions
1950 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1953 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1954 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1955 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1956 and av_fifo_realloc2.
1957 In addition, the order of the function arguments of av_fifo_generic_read
1958 was changed to match av_fifo_generic_write.
1959 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1960 applications, they may not use sizeof() or directly access members.
1962 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1963 Introduce a new metadata API (see av_metadata_get() and friends).
1964 The old API is now deprecated and should not be used anymore. This especially
1965 includes the following structure fields:
1966 - AVFormatContext.title
1967 - AVFormatContext.author
1968 - AVFormatContext.copyright
1969 - AVFormatContext.comment
1970 - AVFormatContext.album
1971 - AVFormatContext.year
1972 - AVFormatContext.track
1973 - AVFormatContext.genre
1976 - AVProgram.provider_name
